GRASP: A PLANT TRANSFORMATION-INDEPENDENT CRISPR-BASED SYSTEM FOR AFFINITY PURIFICATION OF SPECIFIC CHROMATIN LOCI

This paper introduces GRASP, a transformation-independent CRISPR-based method that utilizes dCas9-gRNA ribonucleoprotein complexes to directly capture and purify specific chromatin loci from native plant nuclei, enabling efficient, sequence-specific isolation of genomic regions and their associated components without the need for transgenic expression.

CRISPR-Cas immune repertoires as an ecological record of bacterial interactions with mobile genetic elements in the human gut

By analyzing fecal metagenomes from 1,034 individuals, this study constructs a comprehensive resource of gut bacteria, viruses, and plasmids to demonstrate that CRISPR-Cas immune repertoires primarily record local, cohort-specific interactions between bacteria and mobile genetic elements rather than reflecting direct human host characteristics.

Ischemia-Induced Post-Translational Modifications of GLT-1 Mediate Aberrant Trafficking and Impaired Glutamate Uptake

This study demonstrates that ischemia-induced ubiquitination of the astrocytic glutamate transporter GLT-1 triggers its aberrant internalization and degradation, leading to impaired glutamate uptake, and shows that blocking this post-translational modification restores surface expression and provides neuroprotection.

Validation of a molecular workflow for Cochliomyia hominivorax (New World screwworm) identification in field samples

This study develops and validates a comprehensive molecular workflow comprising three highly sensitive real-time PCR assays and five Sanger primer sets to provide rapid, accurate, and verified species identification for the reemerging New World screwworm (*Cochliomyia hominivorax*), thereby enhancing surveillance capabilities for potential incursions into the United States.

State of mangrove biodiversity assessment in Kenya and the prospect of environmental DNA in strengthening surveys

This study evaluates the current state of mangrove biodiversity assessments in Kenya through a systematic literature review and a pilot environmental DNA (eDNA) survey, revealing significant spatial biases in existing data and demonstrating that eDNA offers a complementary approach to expand taxonomic detection, provided that regional reference databases and standardized frameworks are developed.

Spatial Transcriptomics of TNBC tumours and corresponding lymph node metastasis reveals immune hubs driven by TNF/NF-κB signalling of TMSB4X and CD74 expressing cells.

This study utilizes spatial transcriptomics to demonstrate that TNBC lymph node metastases are characterized by expanded TNF/NF-κB-driven immune hubs centered on TMSB4X and CD74-expressing cells, which coordinate myeloid-endothelial crosstalk to promote metastatic persistence.
